Application & Compatibility
The HY-PRO HP03DNL4-1MB is designed for use in hydraulic and lubrication filtration systems. With a 3µm rating, this element is suitable for servo valve protection and high-precision hydraulic systems. Nitrile (Buna-N) seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 450 PSID collapse rating indicates the maximum differential pressure this element can withstand during cold starts or bypass conditions without structural failure. Ensure your system's maximum differential pressure does not exceed this rating.
